winter project officially underway

The new clutch MC install marks the start the winter recon of my 81 240d.
I now have the pleasure of the following repairs: new Bilsteins all around,
fixing the various vacuum issues, ebrake adjuster repair, adjust the valves and linkages, pull the injectors, test them and proceed accordingly and most importantly, tracking down and fixing the periodic driveline growl that came with the car. I hope it is the driveshaft carrier
bearings and not the differential but I do need to figure it out.
All in all it looks to be a fine way to while away the rest of the winter along with those powder days snowboard riding and the usual daily firewood handling and stove and furnace feedings.
This is what Benz owning is all about. When your not out on the road enjoying driving them you can be in the shop enjoying working on them.

Update

Well today I painted the right front fender with POR15 and will start rust hole repair when dry. I already have done some paint damage and rust repair from the leaking clutch MC.
Put the freshly cleaned and tested injectors back in with new viton return lines for future BD use, reassembled all the unhooked hardware, bled the fuel system and fired it up.
I then could check out the smooth operation of the newly repaired door lock vac system. 2 vac actuators replaced.
Clutch MC replaced, bled and tested.
Installed new front seal and belt adjuster on the PS pump.
Replaced trans,diff, engine oil, ps and brake fluid.
New Bilstein comforts all around.
Repaired rt rear ebrake adjuster
New shift boot
Replaced left rear taillight and seal
Still have rust and paint repair to do on drivers side floor from the leaky MC and in the trunk from the cracked leaky left rear tailight lens
And last but not least I have to track down the growly sound from the driveline that occurs only when letting on or off the throttle.
While it was up on stands I put the car in gear and ran it while looking and listening under the car. No obvious noises, driveshaft carrier and flex discs look and feel ok. Seems to be a small amount of DS rotary play and minimal endplay but nothing excessive.
Rt rear wheel has a fractional side to side play though no top to bottom but wouldn't a bad bearing be constantly noisy?
Looks like original axles and the boots are looking dry but not cracked through.
Still it is coming along great and I am psyched to drive it again.
More to come

you have been busy, hope you find the growl. I hate those intermitant problems

Well, you start going on one of these MB's and it becomes a treasure hunt.
Yesterday I was bolting the rt frt fender back down after body repair and paint and I began eyeballing the whole inner wheel area for issues and noticed the major rust and rot along the under bumper apron/valance strip.
That of course led across to the left frt fender and the same rust rot condition.
So I removed fender liners and bumper end rubbers which exposed the rusting bumper rubber brackets.
I spent the rest of the day doing rustoration with POR 15 products.
Today, I began body and final paint work and noticed a puddle of antifreeze beneath the rad.
I think my demo and prep of the rust may have shaken or somehow moved and stressed something in the rad and opened a small crack or hole.
Which leads to my question.
Should I just buy new or is a local recore a good option?
I will post this as a separate thread.
